Do I dare hope?

I went out at 7 am today to do a quick visual check of my package hive.  Without the protection of my suit and veil I didn't want to run the risk of getting stung unnecessarily. 

In the past few weeks I've rarely seen any activity outside this weak hive unless there was a robbing frenzy so I wanted to see what, if any, changes were visible since the addition of my homemade robbing screen. 

The front entrance was abuzz with bees leaving the hive!  And not only that but I also saw an invading bee fly up to the hive, land on the screen, walk around on it like it was confused and then fly off.  This bee wasn't a honeybee, it looked more like a bumblebee but I'm not sure what it was exactly.  Had I thought there would be anything to look at I'd have taken my camera with me.

Later today I'm going to check to see if they need more 1:1 syrup, if they took all 4L that I put in there the other day I'm going to be amazed.  My mentor said that maybe I should buy a nuc hive to overwinter these bees, that they'd do better in a smaller environment.  That sounds good but when I checked Brushy Mountain's site, this was a 10 frame nuc hive and I have an 8 frame setup.  I have to make sure that my current frames would transfer over to the new hive plus if the current frames do fit I'd have to put in two frames with bare foundation that would need to be drawn out (in addition to the frames that are already in the hive that need to be drawn out as well).  It's an uphill battle, for sure.

Do I dare have hope for this hive?
